Motorola MB8600 for 400 Mbps
I am currently in 200 Mbps plan and considering to upgrade the service to 400 Mbps. After research and reference check of supported Modem list (https://www.spectrum.net/support/internet/compliant-modems-spectrum-network/), I bought Motorola MB8600, which is future proofing and Docsis 3.1. Surprisingly, the customer service told me that the device is not supporting 400 Mbps speed and trying to sell Spectrum's own device (of course, it would be surcharged). This is not right because the website already indicated the MB8600 is able to handle higher speed. Besides, my account has incorrect device info. It still shows legacy modem TM822A, which i have already swap with MB8600. If you based on the older device to determine whether it is compatible with the upgrade, it will lead to you wrong decision. Have said so, I am just stuck here and has no clue what to do next. Is there any tech support hotline to contact to resolve the issue? It would be appreciated someone from Spectrum side could offer a solution to this soon.
